ARCHITECTURA,
the Art or Science of Building. Architecture is divided into Civil and Military: Civil Architecture teaches to make any Buildings whether pub∣lick or private, sacred or profane: Milita∣ry Architecture teaches to fortifie Cities, Pas∣ses, and Sea-ports. Architecture, says Vitruvius, is a Science, which should be accompanied with great variety of Studies, and requires a vast compass of Learning; for by this means it must judge of all the Works of other Arts: In effect Architecture, or the art of Building comprehends all Sciences, and therefore the Greeks gave it a Name, which signifies a su∣periority, or superintendence over all the rest; and when Cicero would give an Exam∣ple of a Science that is of a vast extent, he instances in Architecture.
This Art, like all the rest, had but weak and imperfect beginnings, and was not per∣fected till after long use and experience. At first Houses were made only for necessity; and because in the first Ages Men often chang'd their Habitations, they did not trou∣ble themselves to make their Houses either beautiful or lasting. But when in process of time, every one endeavour'd to settle in some particular Country, then Men began to build their Houses, more solid and strong that they might be able to hold out against the injuries of time: At last, when Luxury was spread among the most rich and power∣ful Nations, then they began to mind the Beauty and magnificence of their Buildings and having observ'd what contributed most either to the Strength or Beauty of them, they set down Rules about them, and so fram'd the Art of Building well, which is call'd Architecture, as those who are perfect Masters of this Art are call'd Architects.
The necessity of making several sorts of Buildings first induc'd the Workmen to settle different Proportions, and from these diffe∣rent Proportions they compos'd different Or∣ders of Architecture. The Orders which the Ancients established at several times and upon divers accidents are the Tuscan, the Do∣ric, the Ionic, the Corinthian, and the Composite. That which forms each of these different Or∣ders, is the Column with its base and Capi∣tal, and the Entablature, i. e. the Architrave, the Frise and Cornish; for these are the only parts which in Buildings constitute that which is call'd an Order, and each Order has its own peculiar measures. Vitruvius is the most ancient of all the Architects whose Wri∣tings we have; he liv'd in the time of Julius Caesar and Augustus, and had view'd the state∣ly Edifices which were then in Greece and Ita∣ly. Several learned Men have also written many excellent Volumes of Architecture, as Fussitius, Varro, Septimius and Gelsus; and Cos∣sutius a Roman Citizen was sent for by King Antiochus, to finish the Temple of Jupiter Olympius in the City of ••hens.
The Original of the Tuscan Order was in Tuscany, one of the most considerable parts of Italy, whose Name it still keeps. Of all the Orders this is the most plain and least or∣namental: 'Twas seldom us'd, save only for some Country Building where there is no need of any Order but one, or else for some great Edifice, as an Amphitheatre, and such like other Buildings. The Tuscan Column is the only thing that recommends this Order. The Doric Order was invented by the Dorians a People of Greece, and has Columns which stand by themselves, and are more ornamen∣tal than the former. The Ionic Order has its
